[0001] The utility model belongs to the technical field of fire door processing, and mainly relates to automatic positioning and punching equipment for the production and processing of fire doors. Background Art

[0002] Fire doors are doors with certain fire resistance and heat insulation, which can prevent the spread of fire and increase the survival rate of trapped people. During the production process of fire doors, holes are usually punched in the fire doors to facilitate their installation.

[0003] A Chinese patent document with authorization announcement number CN213382062U discloses an automatic punching device for a fire door. The patent includes a frame, a puncher arranged on the frame, and an operating table arranged on the frame. An automatic clamping device is arranged on the operating table. The automatic clamping device includes a clamping plate for clamping the fire door and a driving assembly for driving the clamping plate to fix the fire door. The driving assembly is arranged on the operating table, and the clamping plate is arranged on the driving assembly. A plurality of clamping plates are arranged along the length direction of the operating table, and two adjacent clamping plates squeeze and clamp the fire door.

[0004] Although the patent can achieve drilling, the conveyor belt needs to be stopped when drilling, and the conveyor belt needs to be started again after the drilling is completed, and then the conveyor belt needs to be controlled to move the fire door away.

Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0036] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0037] Example 1

[0038] like Figure 1-Figure 4 As shown, the automatic positioning punching equipment for the production and processing of fire doors includes a base 1, a conveying mechanism 2, a bracket, a rack 6, a mounting frame, a limit mechanism, a punching mechanism, a drive motor 12 and a controller. The limit mechanism presses against the front end of the fire door 3, so that the punching mechanism can move synchronously with the fire door 3, thereby achieving punching without stopping the conveying. The drive motor 12 is used to reset the punching mechanism, and is only used for resetting. When punching, the drive motor 12 is not started.

[0039] Specifically, the conveying mechanism 2 is assembled on the base 1, and the conveying mechanism 2 can convey the fire door 3 along the front-back direction. The conveying mechanism 2 can be a belt conveyor or a conveying roller conveyor.

[0040] Specifically, the bracket includes a front support frame 4 and a rear support frame 5, both of which are fixedly mounted on the base 1, and the area between the front support frame 4 and the rear support frame 5 is the punching area of ​​the fire door 3. The front support frame 4 and the rear support frame 5 each include two legs and a crossbeam, the legs extend in the vertical direction, the two legs are located on both sides of the conveying mechanism 2, and the crossbeam is mounted on the upper ends of the two legs.

[0041] Specifically, there are two racks 6 which are parallel to each other, and the extension direction of the two racks 6 is consistent with the conveying direction of the conveying mechanism 2. The two racks 6 are slidably mounted on the crossbeam. At the same time, the two racks 6 are mounted with a connecting beam 18, and the two racks 6 are formed into a whole by the connecting beam 18, which increases the synchronization of the two racks 6.

[0042] The mounting frame includes a front frame 19 and a rear frame 7, both of which are fixedly mounted between two racks 6, and a punching mechanism is mounted on the front frame 19. The limiting mechanism includes a cylinder 11 and a limiting frame 20, one end of which is hinged on the front frame 19, and the other end of which is used to press the front end of the fire door 3 so that the punching mechanism is synchronized with the fire door 3. The fixed end of the cylinder 11 is hinged on the rear frame 7, and the telescopic end of the cylinder 11 is hinged on the limiting frame 20. The hinge of the limiting frame 20 and the hinge of the cylinder 11 are both rotated around an axis extending in the left and right directions.

[0043] Specifically, the punching mechanism includes a cross slide and a puncher 10, the cross slide includes an X-axis slide 8 and a Y-axis slide 9 moving on the X-axis slide 8, the X-axis slide 8 is installed on the front frame 19, the X-axis slide 8 extends in the left-right direction, the Y-axis slide 9 extends in the up-down direction, the Y-axis slide 9 has a slider 21, the slider 21 can move in the up-down direction on the Y-axis slide 9, the puncher 10 is installed on the slider 21, so that by setting the Y-axis slide 9 to move on the X-axis slide 8, the puncher 10 can punch multiple holes in the same direction. The specific structure of the cross slide has a lot of descriptions in the prior art, so it will not be repeated in this embodiment.

[0044] The drive motor 12 can be installed on the front support frame 4 or the rear support frame 5. The output end of the drive motor 12 is equipped with a gear 13 meshing with the rack 6. The drive motor 12 is used to reset the punching mechanism. At the same time, a one-way bearing is installed between the gear 13 and the output end of the drive motor 12, so that the drive motor 12 can only drive the rack 6 to move in one direction, that is, when the punch 10 needs to be reset, the drive motor 12 drives the rack 6 on the corresponding side to move, so that the punch 10 returns to the front side. The specific structure of the one-way bearing has been described in detail in the prior art, so it will not be repeated in this embodiment.

[0045] The controller is a PLC, which is electrically connected to the cross slide, the drive motor 12 and the cylinder 11 to control the corresponding actions of the cross slide, the drive motor 12 and the cylinder 11.

[0046] When the fire door 3 moves backward on the conveying mechanism 2, the cylinder 11 will lower the limit frame 20 so that the limit frame 20 contacts the fire door 3, thereby driving the components on the two racks 6 to move backward as a whole. At this time, the punching mechanism will move synchronously with the fire door 3 while punching. After the punching is completed, the cylinder 11 pulls up the limit frame 20, and the punching mechanism will no longer move synchronously with the fire door 3. After that, the PLC will control the drive motor 12 to drive and send the punching mechanism back to the front to achieve reset, thereby achieving punching without stopping the conveying.

[0047] The front support frame 4 is provided with a front connecting member 14, on which a front proximity switch 15 is installed, and the front proximity switch 15 is used to detect the position of the front frame 19. The rear support frame 5 is provided with a rear connecting member 16, on which a rear proximity switch 17 is installed, and the rear proximity switch 17 is used to detect the position of the rear frame 7. The front proximity switch 15 and the rear proximity switch 17 can detect the position of the mounting frame to prevent the punching mechanism and the limit mechanism on the mounting frame from colliding with the bracket.

[0048] In order to enable the two racks 6 to move synchronously, two drive motors 12 may be provided, and the racks 6 on the corresponding sides may be driven respectively by the two drive motors 12 .

[0049] Example 2

[0050] The difference between this embodiment and the first embodiment is that in this embodiment, there are multiple front frames 19, the number of which is the same as the number of rows to be punched, and the multiple front frames 19 are sequentially installed between the two racks 6, and the distance between adjacent front frames 19 can be determined according to the positions to be punched on the fire door 3. A punching mechanism is installed on each front frame 19, and the limit frame 20 is only installed on one front frame 19 close to the rear frame 7. In this way, by setting multiple punching mechanisms, multiple positions on the fire door 3 can be punched.
